A word must be said to those whose bereavement is increased by some doubt about the loved one's spiritual condition. I write these words prayerfully and sensitively, because there are Christians having lost such, have carried with them a sense of numbness ever since.
They have re‑examined the Scriptures on Judgement to see what they really mean, and have tried to recall any incident during their lifetime that indicated any response to God. They have desperately hoped that even in their dying hours they made their peace with God.
I remember a couplet of a poem where a Godly woman was exercising herself in the same way when she heard that her unbelieving husband had been killed when riding his horse. Her hope was that "between the saddle and the ground, he mercy sought and mercy found".
We cannot however, offer false comfort; having preached the necessity of repentance and faith in the Lord Jesus for salvation, we cannot give the impression that we only half believe it.
I think that there is only one thing to be done in such circumstances. It is for the mourners to present themselves before God, pour out their hearts and let Him take their grief, and find rest in the fact that God is judge and a righteous one. He has all the facts, and in his absolute justice and righteousness He decides destiny, and however difficult we may find it, the believer can find peace in saying 'Amen' to all God's righteous judgements.
